Absorption, Distribution and Excretion
Rarely, absorbed into the blood stream if used as a combination with other ingredients in suppository form. But, Applying cream or ointment form to open wound or skin may lead this drug to absorb and circulate into blood stream. Metabolism / Metabolites After oral administration of esculin (100 mg/kg) for rats, plasma, urine, feces and bile samples were collected to screen metabolites. As a result, a total of 19 metabolites (10 phase I metabolites and 9 phase II metabolites) were found and identified. It was also found that after oral administration of esculin, the esculin could be metabolized to esculetin in vivo via deglycosylation, and esculetin was found in all biological samples. Biological Half-Life Absorption half life about 1 hour and elimination half life about 20 hours |

| Additional Infomation |
Esculin is a hydroxycoumarin that is the 6-O-beta-D-glucoside of esculetin. It has a role as an antioxidant and a metabolite. It is a beta-D-glucoside and a hydroxycoumarin. It is functionally related to an esculetin.
Esculin is found in barley. Vitamin C2 is generally considered a bioflavanoid, related to vitamin P esculin is a glucoside that naturally occurs in the horse chestnut (Aesculus hippocastanum), California Buckeye (Aesculus californica) and in daphnin (the dark green resin of Daphne mezereum). Esculin belongs to the family of Glycosyl Compounds. These are carbohydrate derivatives in which a sugar group is bonded through its anmoeric carbonA to another group via a C-, S-,N-,O-, or Se- glycosidic bond. Esculin has been reported in Gardenia jasminoides, Ixeridium laevigatum, and other organisms with data available. A derivative of COUMARIN with molecular formula C15H16O9. See also: Horse Chestnut (part of); Aesculus hippocastanum bark (part of). Drug Indication As medication, esculin is sometimes used as a vasoprotective agent. Esculin is also used in a microbiology laboratory to aid in the identification of bacterial species (especially Enterococci and Listeria), as all strains of Group D Streptococci hydrolyze æsculin in 40% bile. Mechanism of Action The main activities of Esculine focus on capillary protection, as it improves capillary permeability and fragility. It is reported to inhibit catabolic enzymes such as hyaluronidase and collagenase, thus preserving the integrity of the perivascular connective tissue. Esculine also showed good antioxidant properties, protecting triglycerides against auto-oxidation at high temperatures . The antioxidant property might as well explain some of the anti-inflammatory activity of the product, making it a suitable product for after sun treatments, for example. Pharmacodynamics Topically applied Esculine increases the “capillary density” (the number of capillaries open to flow per surface unit) and improves the morphological aspect of the smallest blood vessels. |

Note: Listed below are some common formulations that may be used to formulate products with low water solubility (e.g. < 1 mg/mL), you may test these formulations using a minute amount of products to avoid loss of samples.
Injection Formulations
Injection Formulation 1: DMSO : Tween 80： Saline = 10 : 5 : 85 (i.e. 100 μL DMSO stock solution → 50 μL Tween 80 → 850 μL Saline)(e.g. IP/IV/IM/SC) *Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH ₂ O to obtain a clear solution. Injection Formulation 2: DMSO : PEG300 ：Tween 80 : Saline = 10 : 40 : 5 : 45 (i.e. 100 μL DMSO → 400 μLPEG300 → 50 μL Tween 80 → 450 μL Saline) Injection Formulation 3: DMSO : Corn oil = 10 : 90 (i.e. 100 μL DMSO → 900 μL Corn oil) Example: Take the Injection Formulation 3 (DMSO : Corn oil = 10 : 90) as an example, if 1 mL of 2.5 mg/mL working solution is to be prepared, you can take 100 μL 25 mg/mL DMSO stock solution and add to 900 μL corn oil, mix well to obtain a clear or suspension solution (2.5 mg/mL, ready for use in animals).
